comment Halachot of burial vs. minhagim thereof
The term "forbidden" seems rather extreme for pictures. Here in Israel some communities have a custom of a laser engraved picture of the deceased on the headstone. Most (but not all AFAIK) Hevrot Kadisha accept this.

comment May a nutrition scientist perform research on chametz as part of his job on Hol Hamo'ed Pesach?
Not neccesarily a nutrition scientist. An analytical chemist may also have the problem. Indeed, I remember about 33 years ago seeing a bottle of acetic acid in the lab clearly stamped as Chametz - not for use on Pesach.

comment Making Kiddush with Grape Juice or White Wine
I seem to remember having heard of a custom to start the seder with red wine (symbolizing the blood of slavery) and end with white wine (symbolizing the purity of freedom and Torah), with the intermediate cups mixed. (Note - the reverse for seder Tu Bishvat - white for winter and cold progresses to red for summer, heat and life)

comment Is there any evidence of time-zones in Talmud? (Tanaim and Amoraim only)
@Ronen This relates to height and not time zones which are a longitude variation. Zippori is not far enough away from Tiberias for there to be a significant difference in solar time.

comment What will Lubavitchers do in 2052?
I suspect that the answer would be that the Moshiach will arrive by then.

comment Can a father name his son Esau?
I learnt (IIRC indirectly from the Lubavitcher Rebbe) that the naming of a son is the only chance ordinary Jews have for prophecy. If a father named his son Esau, presumably this would reflect on the life of the son. It seems to me a strange choice, but so do Nimrod and a few others, even Nadav and Avihu. I wouldn't expect it, but I'm not sure there is a prohibition, if the father insisted even after it was explained to him that maybe it's not appropriate.

comment Can wasabi be used for maror at the seder?
@DoubleAA - Isn't horseradish a root though? It certainly looks like one.

comment Marijuana for B'Samim at Havdallah?
Probably was, but since it grows naturally in the area you never know. A lot of people have picked up on the link however. Of course, kneh bosem was part of the anointing oil (shemen hamishchah) and not the ktoret

comment Marijuana for B'Samim at Havdallah?
1) I read somewhere that there is an opinion that "kneh bosem" is cannabis (presumably due to similar sound). I don't know whether there is hard evidence one way or the other. 2) At least as far as the ktoret was concerned, there were unpleasant smelling items included.

comment Honor a first-time blood donor during shacharit?
You can always do a Mi shebeach for Holim (standard text) and add "those who received blood donations especially that of....". This has the advantage to my mind of reinforcing blood donations in general as well as praising the specific donor. Presumably 6-12 refers to grades, not ages.

comment How should a werewolf celebrate Pesach?
If the full moon falls on leil haseder and the person involved has already eaten the Afikoman, is he then allowed to drink the Benny's Bane afterwards, and if not, does the ptror from Kriyat Shma still hold?

comment How does one say kaddish if he is in the middle of amidah?
I got the impression that @NS23 is referring to a mourner who is late and should say kaddish, not just respond. AFAIK, the answer is that he can't interrupt the Amidah to say kaddish. If he has finished and said yiyhiu ratzon, but not yet stepped back and said Oseh shalom, there may well be grounds to permit him to say kaddish since he is in the same state as the Shat"z, and his steps back at the end of kaddish serve also for the Amidah.

comment Should one make a bracha on seeing geological arches, hoodoos or balanced rocks?
If in doubt then say "oseh maaseh bereshit" without Shem and Malchut.

comment Is it okay to sing Zemirot for Shabbas day on Shabbas night?
Surely the nights are longer in winter and shorter in summer, whilst the day is longer in summer whereas in winter there is hardly time for a rest before seudah shlishit

comment Prohibition against leaving a laundry machine running into shabbos?
@Fred - The machine we bought recently beeps at the end of the run and you have to select off or open the lid to stop it. That's what made me mention it - Shabbat full of beeping ........

comment Prohibition against leaving a laundry machine running into shabbos?
It also has to be assumed that the machine is not one that needs actual turning off and that the act of opening the lid will not cause a melacha. Also, is opening the lid preparation from Shabbat to Hol and are you (under suitable circumstances) allowed to hang the washing? So the washing has to stay in until Motsash? Is there any point?

comment Was the noise from the Temple really that loud?
How does the Ra'avad reconcile the lack of mountains as obstructions with "Yerushalayim harim saviv lah"?

comment Kashering frozen meat
Frozen meat that had not been salted was imported to Israel under Rabbanut hechsher, but in recent years the meat has been salted before import (presumably before freezing).

comment Would there be any maaser derabbanan on hydroponically grown plants?
AFAIK hydroponically grown produce is not covered by Shemitta restirctions. Logically, therefore, I would expect that there is no requirement for maaser.
